3 Claims.

This invention relates to a receptacle for liquids and has specialreference to a sealing means between an open end of a receptacle and acap for enclosing the same in which the sealing means may function as adrip edge to return the liquid accumulated at the open end of thereceptacle back into the receptacle.

More particularly, this invention relates to a receptacle for liquidscomprising a rigid main body portion having an open upper end withconnecting means on the outer periphery thereof and a rigid cap forenclosing the open upper end having an internal recess with connectingmeans therein co-operating with the connecting means of the main bodyportion for detachable engagement therewith, a rigid extension on thecap within the recess seating within the bore of a band of resilientmaterial frictionally engaging the open end of the main body portion toseal the contents of the receptacle and to provide an internal drip edgefor directing liquid accumulated at the open end back into thereceptacle.

It may be desirable to provide a fin extending axially of the rigidextension down into the open end of the bottle preferably below thesealing band for automatically breaking any bubble that may have formedaround the open end of the bottle as the cap is removed to avoid thesplatter of fluid which would ordinarily result if the bubble werebroken through the insertion of a pen or other means after the cap hasbeen removed. The bubble is broken upon removing the cap and beforeactual removal thereof so that the breaking of the bubble and subsequentsplattering will be retained within the open end of the receptacle andsuch accumulated liquid as may result from the splattering will dripback into the receptacle.

This invention also contemplates a band of resilient material employedbetween the receptacle and the cap having an integrally formed inwardlyextending peripheral lip and an outwardly extending integrally formedflange together with an integral wall extending across the inner borethereof, the flange engaging a groove in the open upper end of thereceptacle for maintaining the band in a fixed position and the wallforming a well to be filled by tilting the receptacle with the lipengaging a substantial rigid extension of the cap to effect a sealingengagement between the side walls of the extension and the inner bore ofthe lip, whereby the lip function as a sealing means and a drip edge.

One of the uses to which the present container may be employed is thatof holding writing ink and that use particularly in the instance ofcarrying the container in a grip together with wearing apparel.Traveling salesmen, tourists and others are confronted with the problemof carrying a writing fluid in the same container with their wearingapparel, and everyone generally encounters it occasionally. Thereceptacle of the present invention, besides being leakproof, mustretain displaced ink in the receptacle and not permit the same to soilthe outer surfaces of the receptacle after the stopper has been removed,the ink used and the stopper replaced.

One of the objects of this invention is to provide a receptacle of thecharacter indicated above in which the sealing means thereof mayfunction as a drip edge to return the ink within the receptacle'andprevent the same from being attracted to the outside of the receptacleto soil the threads and outer surfaces thereof.

A further object of this invention is to provide a receptacle of. thetype hereinabove described in which the sealing means may be resilientand may be readily inserted into the open end of the receptacle in afixed relation therewith.

A still further object of this invention is to provide a receptacle ofthe type above referred to in which a fin is disposed on the extensionof the cap to break any air bubble formed at the open end of thereceptacle prior to the cap being removed from the open end thereof toprevent splattering of liquid upon subsequent use of the receptacle indipping a pen or other object thereinto.

Another object of this invention is to provide a receptacle as indicatedabove in which the sealing means may be so constructed and arranged asto provide a well which may be quickly and easily filled when the cap isin position on the receptacle by tilting or inverting the receptacle.

Astill further object of this invention is to provide a receptacle ofthe type above referred to which is simple in operation, is inexpensiveto manufacture, and is durable.

Otherobjects and advantages will hereinafter be more particularlypointed out and for a more complete understanding of the characteristicsof this invention, reference may now be had to the following descriptionwhen taken together with the accompanying drawings, in which latter:

Figure l is a top plan View of a receptacle embodying the features ofthis invention with the cap thereof removed;

Fig. 2 is a central vertical sectional View of the receptacle of Figure1 with the cap thereof in position thereon;

Fig. 3 is a central vertical sectional view of a upper end of thecontainer.

modified form of receptacle construction embodying the features of thisinvention;

Fig. 4 is a central vertical sectional view taken on the line 44 of Fig.3;

Fig. 5 is a central vertical sectional view of another form ofreceptacle embodying this invention with a portion of the receptaclebroken away; and

Fig. 6 is a view similar to Fig. 5 of still another form of receptacleembodying the features of this invention.

Referring now to the drawings, and more particularly to Figs. 1 and 2thereof, one of the constructions shown as embodying the features ofthis invention comprises a receptacle I0 having an open upper end withconnecting means such as threads H on the upper and outer peripherythereof, the threaded portion being preferably a reduced extension ofthe main body portion. A cap I2 is provided for enclosing the open upperend of the receptacle ii) and is preferably interiorly threaded forengaging the threaded open The outer diameter of the cap is preferablythe same as the outer diameter of the receptacle for purposes ofappearance and convenience in handling.

The material of the container and cap may be of hard rubber, or of acellulose composition or material such as is known to the trade asradite, Bakelite, and the like, the latter materials being preferablewhere ornamentation or color effects may be desired. However, it is tobe understood that the receptacle may be of glass, or, if desired, maybe of glass covered with a thin shell of composition.

A'sealing means i3 is provided between the receptacle and the cap andpreferably comprises an annular bandhaving an outer diametersubstantially the same as that of the inner diameter or bore of theupper open end of the receptacle ii] for purposes of a sealed frictionalfit. However, in order to maintain the resilient band in a desired fixedposition, an ,outwardly extending for the ink to freely pass from themain body portion of the container into the Well.

In the use of the receptacle as an ink receptacle and well, thereceptacle is filled with ink and capped in the usual manner. When thewell is to be used, the receptacle is tilted or inverted be fore the capis removed and the well allowed to fill, after which the receptacle isplaced upright and the cap removed. When the ink is to be used forfilling fountain pens, the fountain pen is inserted into the pocket orWell with the edge or end of the barrel resting against the top of thewall l8.

After the use of the receptacle for filling fountain pens, or any otheruse thereof, the receptacle is capped in the usual manner by threadingthe cap so that the extension I! of the cap engages the resilientinwardly extending lip iii. In the sealing of the receptacle, a veryefiicient adjustable .type is had in the present invention, the

threads taking up wear, if any, and affording a very tight liquid seal.This sealing takes place within the neckof the receptacle where suchsealing action is most desirable, the seal being formed as a peripherallip. It functions as a drip edge to direct surplus or displaced liquidback into the container and avoids a displacement thereof on the outsideto soil the threads exteriorly of the receptacle as well as the exteriorsurfaces thereof. Such a sealing means may be constructed and arrangedas to readily provide a preferably integrally formed flange I4 is formedH on the periphery of the band which flange engages a peripheral groovel5 of the inner bore of the receptacle iii. The sealing means I3 ispref- .erablyfformed of soft rubber and is thereby resilient.

It may. be compressed or distorted in such a manner that it may bereadily and conveniently inserted from the open upper end and moveduntil the outwardly extending flange l4 registers with the groove l5,whereafter the flange will snap into engagement therewith.

The upper end of the sealing means or band i3 is provided with apreferably integrally formed inwardly extending lip It for engagementwith the side walls of a substantially rigid extension i! formedinteriorly of the cap l2. The side walls of the extension H preferablyconverge when viewed in cross section and in this manner are adjustablyassociated with the inwardly extending lip by reason of the movementvertically or the receptacle by means of the engaged threads of thecapand receptacle.

It is desirable, when the receptacle is used for containing ink forfilling fountain pens, that an integral wall It be extended across theinner bore well for the purpose, as above described, of filling afountain pen. The seal thus formed, may be readily applied to areceptacle inasmuch as it is soft and yielding although stiff enough tobe fixed in position unless manually forced.

Referring now more particularly to Figs. 3 and 4 of the drawings, themodified form of construction therein showncomprises a receptacle 20having an open upper end with connecting means such as threads 2| on theupper and outer peripheries thereof, the threaded portion beingpreferably a reduced extension of themain body portion. A cap 22encloses the open upper end of the receptacle 2B and is provided with arecess having connecting means such as threads 23 for engaging thethreaded open upper end of the container. The outer diameter of the'capis preferably the same as the outer diameter of the receptacle forpurposes of appearance and convenience in boxing and handling. As in thepreviously described embodiment of this invention, thematerial of thecap and of. the main body portion of the receptacle is comparatively.rigid.

A sealing means 24 is provided betweenthe open end of the receptacle andthe cap and pref erably comprises an annular band or collar having aradially extending flange 25 formed integrally therewith at one endthereof. The outer diameter of the annular band of the sealing means 2 3is-preferably such as to form a tight fit with the material employedpreferably being of soft rubber or other like resilient material. Theflange 25 maintains the sealing means 24 in a desired fixed positionwithin the openend of the receptacle. By reason of the sealing meansbeing resilient it may be compressed or distorted in such a manner thatit maybe readily and conveniently inserted into the open upper endof{the receptacle and moved to a positionsuch that the radially extendingflange.. 25 engages the end of the receptacle Whereaf ter. thedistortedmaterial of theband will snap into frictional engagementtension 26 preferably formed integrally with the cap and of rigidmaterial, the side walls of the cap preferably converging as at 21 toextend into the collar of the sealing means 24 and to seat thereon. Afin 28 extends from the extension 26 through the collar of the sealingmeans and preferably on the other side thereof to break any bubble whichmay have formed across the open end of the receptacle automatically uponremoval of the cap. The tapered on converging side wall 26, upon removalof the cap, breaks contact with the bottle quickly to avoid forming aperipheral capillary that may be inclined to draw the fluid outside ofthe neck of the bottle. The fin 28 is preferably pointed and V-shapedwhen viewed in one direction and is comparatively thin for performingits function in an efficient manner.

Referring now more particularly to Fig. of the drawings, a constructionvery much similar to that of Fig. 2 is shown comprising a receptacle 29having an open upper end with connecting means such as threads 30 on theupper and outer periphery thereof, the threaded portion being preferablya reduced extension of the main body portion. A cap 3| encloses the openupper end of the receptacle 29 and i preferably interiorly threaded forengaging the threaded open upper end'of the container. The container andcap therefor are of a substantially rigid material such as hard rubberor the like as hereinbefore mentioned.

A sealing means 32 is provided between the receptacle and the cap andpreferably comprises an annular band 33 having an outer' diametersubstantially the same as that of the inner diameter or bore of theupper open end of the receptacle 29 in order to assure a sealedfrictional fit. However, in order to maintain the resilient band in adesired fixed position, an outwardly extending preferably integrallyformed flange 34 is formed on one end of the collar 33 to engage aperipheral groove 35 on the inner bore of the receptacle 29. As in theprevious embodiments of this invention, the sealing means 32 ispreferably formed of soft rubber or like resilient material so that itmay be inserted conveniently into position at the open upper end of thecontainer and held therein against displacement.

An extension 36 is formed preferably integrally on the inside of the cap3| the side walls of the extension 36 tapering or converging when viewedin cross section to extend into the collar and seat thereon. A fin 31likewise preferably formed integrally with the cap extends through thecollar and preferably on the other side thereof to form a means forbreaking any bubbles which may form across the open end of thereceptacle. The fin 31 is preferably formed in the same shape as thatpreviously described with reference to the embodiment of Figs. 3 and 4.

The present embodiment disclosed in Fig. 5 differs from that of theembodiment shown in Fig. 2 by the omission of an inwardly extending lipsurrounding the upper end of the collar 33 and the omission of the cupor auxiliary well formed by the sealing means. However, when the cap isto be removed, the initial movement to disengage the connecting membersquickly breaks the seal so as to avoid the formation of a capillarycondition which would ordinarily draw liquid to the point of engagement,and subsequent disengagement of the cap causes the fin to break anybubble which may be formed across the open upper end of the receptacleprior to the complete removal of the cap. The breaking of the bubble isdone internally of the receptacle to obviate splattering fluid on theconnecting means or outside of the receptacle. The walls of thereceptacle may be reinforced in the provision of ribs 38.

The embodiment of this invention as disclosed in Fig. 6 comprises areceptacle 39 having an open upper end with connecting means such asthreads 40 on the upper and outer periphery thereof, the threadedportion being preferably of reduced diameter. A cap 4| encloses the openupper end of the receptacle 39 and is preferably internally threaded forengaging the threaded open upper end of the container. The outerdiameter of the cap 4| is preferably the same as the outer diameter ofthe receptacle for purposes of appearance and convenience in packaging.Both the cap and the receptacle, as in the previously describedembodiments, are of a rigid material such as hard rubber or the like.

The cap 4| is provided with an internal extension 42, the side walls ofthe extension being spaced from the connecting means of the cap to forma channel. A sealing means 43 is disposed in the channel between theextension and the connecting means of the cap, the inner wall of thesealing means frictionally engaging the outer wall of the extension 42with the outer wall of the sealing means being tapered or, in otherwords, when viewed in cross section the edges thereof converge. Theconverging edges extend into the open upper end of the receptacleandseat thereon to seal the contents of the receptacle and to provide aninternal drip edge for directing liquid accumulated at the open end ofthe receptacle back into the main body portion thereof.

A fin 44 of the character of the fins in the previously describedembodiments extends from the extension of the cap into the open end ofthe receptacle and substantially therebelow in order to break any bubblewhich may be formed across the open end of the receptacle as the cap isremoved therefrom.

While several embodiments of this invention are herein shown anddescribed, it i to be understood that various modifications thereof maybe apparent to those skilled in the art without departing from thespirit and scope of thi invention and, therefore, the same is only tobe' limited by the scope of the prior art and the appended claims.
